Package org.apache.commons.io.filefilter

Class FileFileFilter

java.lang.Object
org.apache.commons.io.filefilter.AbstractFileFilter
org.apache.commons.io.filefilter.FileFileFilter
All Implemented Interfaces:
FileFilter, FilenameFilter, Serializable, FileVisitor<Path>, PathMatcher, PathFilter, PathVisitor, IOFileFilter
public class FileFileFilter extends AbstractFileFilter implements Serializable
This filter accepts Files that are files (not directories).

For example, here is how to print out a list of the real files within the current directory:

Using Classic IO

 File dir = FileUtils.current();
 String[] files = dir.list(FileFileFilter.INSTANCE);
 for (String file : files) {
     System.out.println(file);
 }

Using NIO

 final Path dir = PathUtils.current();
 final AccumulatorPathVisitor visitor = AccumulatorPathVisitor.withLongCounters(FileFileFilter.INSTANCE);
 //
 // Walk one dir
 Files.walkFileTree(dir, Collections.emptySet(), 1, visitor);
 System.out.println(visitor.getPathCounters());
 System.out.println(visitor.getFileList());
 //
 visitor.getPathCounters().reset();
 //
 // Walk dir tree
 Files.walkFileTree(dir, visitor);
 System.out.println(visitor.getPathCounters());
 System.out.println(visitor.getDirList());
 System.out.println(visitor.getFileList());
